NUT AND BOLT LOCK.

Specification of Letters Patent.

Patented May 14;, 1912.

Application filed September 22, 1910. Serial No. 583,273.

T 0 all whom it may concern Be it known that I, HARRY HEDDEN, a citizenof the United States, residing at Evans ville, in the county ofVanderburg and State of Indiana, have invented certain new and usefulImprovements in Nut and Bolt Locks; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

This invention relates to improvements in nut and bolt locks and has forits object the provision of means whereby the nut or bolt or both may befirmly secured to the structure to which they are applied and heldagainst accidental separation from such structure or from each other.

With the above and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts as will be more fully described and particularly pointed out inthe appended claim.

I11 the accompanying drawings: Figure 1 is a vertical sectional viewthrough a portion of a box and its cover showing one application of myimproved bolt and nut; Fig. 2 is a top plan view of the bolt and nut asshown in Fig. 1; Fig. 3is an edge view of the nut locking washer shownin Figs. 1, and 2; Fig. 4 is a view similar to Fig. 1 showing anotherform of bolt and nut and means whereby both the bolt and nut arefastened; Fig. 5 is a plan view of the same; Fig. 6 is a side view ofthe nut shown in Figs. t and 5; Fig. 7 is a plan view of the boltfastening ring shown in Figs. 1 and 5; Fig. 8 is a longitudinal sectionof a wheel hub and axle showing an application of the invention forholding the hub retaining cap on the axle.

Referring more particularly to Figs. 1, 2 and 3 of the drawings, 1denotes the bolt which in these figures is shown as a screw bolt havingin its outer end a notch 2 adapted to receive a screw driver wherebysaid bolt may be driven into the object to which it is to be applied.

In the present instance the bolt 1 is shown as being applied to theupper edge of one side of a box for the purpose of fastening the coverthereon and when thus applied the upper end of the bolt is adapted toproject through a suitable opening in the cover and to extend above thecover as shown.

Adapted to be screwed into engagement with the projecting upper end ofthe bolt is my improved nut 3, the inner side of which is preferably setinto a recess t formed in the upper side of the cover as shown. The nut3 in the present instance is shown as being circular in form and in theouter edge thereof adjacent to its lower side is formed an annulargroove or channel 5. The recess 4 in the cover of the box is of suchdepth that when the nut is seated therein the lower wall of the grooveor channel 5 will be flush or on a line with the upper surface of thecover as shown. In the top of the nut and preferably on opposite sidesof the same are formed sockets or recesses 6 which are adapted toreceive a nail or other suitable implement whereby the nut may bereadily turned on the bolt.

Secured to the upper side of the top or cover of the box is a nutretaining washer 7 formed in two semicircular sections, said sectionshaving their meeting ends notched or mortised as shown at 8 whereby whensaid mortised ends are brought together into overlapping engagement theupper and lower surfaces of the two sections will be flush with eachother. In the overlapping ends of the washer are formed alined screwholes through which are inserted fastening screws 9 which are drivendown into the top or cover of the box thereby holding the sections ofthe washer together, as well as fastening the same to the top or coverof the box. When thus applied'to the top or cover the inner edges of thewasher sections engage the annular groove or channel 5 formed in the nutand thereby hold the nut to the cover as will be readily understood onreference to Fig. 1.

In Figs. 4 and 5 of the drawing is shown a slightly modified form ofbolt and nut and a slightly modified form of nut retaining washer. Inthis form of the device the bolt 10 is provided on one end with a head11 which may be of any suitable shape. It is advisable that the bolt 10be rigidly secured to the object through which it passes at its head endand I have shown a fastening means suitable for this purpose. In thebolt at a suitable distance from the head is formed an annular groove orchannel 12, said channel being arranged to occupy a position close tothe inner surface of the object to which the bolt is applied and engagedby a bolt fastening ring or section of a ring 13 which impinges againstthe inner surface of the object towhich the bolt is applied and therebyprevents the casual disengagement or removal of the bolt from theobject.

On the opposite end of the bolt 10 is screwed a nut 16 which may be ofany suitable shape and which is here shown as being rectangular and ashaving formed therein an annular groove or channel 17 corresponding tothe groove 5 formed in the nut 3 of the first form of the invention. Thenut 16 is provided at diametrically opposite points with notches orrecesses 18 which may be engaged by a suitable implement to turn andrelease the nut. In applying this form of the nut, the inner portionthereof is preferably set into a recess or opening formed in the objectto which the same is applied and the groove 17 in the nut is engaged bythe sections of a two-part washer 19 which are also arranged in a recessformed in the outer side of the object, whereby the washer will becountersunk therein as is clearly shown in Fig. 4;. In the outer edge ofthe washer sect-ions are formed notches 20 through which screws orsimilar fastening devices 21 are inserted into the structure to whichthe device is applied whereby the sec tions of the washer are held inengagement with the groove in the nut to retain the nut in place againstaccidental displacement. When it is necessary, however, to remove thenut, the fastening devices may be readily withdrawn by means of suitabletools and the nut and bolt thus disengaged.

In Fig. 10 of the drawings is shown a sectional view through a wheel hubarranged on the end of an axle spindle showing the application of myinvention for fastening the cap or nut on the end of the axle. In thisarrangement of the invention the nut 24: is seated in a recess formed inthe end of the hub and is secured in place by a retaining Washer 25which may be constructed as shown in Figs. 1, 2 and 3 or as shown inFigs. 4 and 5. The sections of the washer 25 in this instance are heldby the ends of the longitudinally disposed bolts 26 which extendentirely through the hub as shown. The bolts 26 are provided on theirouter ends with. beveled heads which fit into countersunk bolt holesformed in the sections of the washer and have applied to their op- Iposite ends countersunk nuts 27 which are provided with oppositelydisposed passages or grooves 28 to receive a suitable implement wherebythe same are screwed on and off the bolts.

From the foregoing description taken in connection with the accompanyingdrawings, it will be seen that I have provided a. very simple device bythe use of which the accidental displacement of a. nut or bolt andrelease and loss of the same will be prevented.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention as defined in theappended claim.

Having thus described my invention, what I claim is:

A device of the character described, the combination with two members tobe clamped, of a bolt secured to one of said members and projectingtherefrom and adapted to pass freely through an opening in the othermember, a nut adjustably mounted on said end of the bolt, said nuthavingan external annular groove. a nut retaining washer the inner edge ofwhich freely engages with the groove formed in the nut, said washerbeing con'iposed of two semi-circular sections having reducedoverlapping ends, and fastening devices passed through said ends of thesections and into the last named member, whereby the nut is revolublymounted upon the latter.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
